| Title of Invention | " A PROCESS FOR THE DISPROPORTION AND TRANSALKYLATION OF TOLUENE AND C9+ HEAVY AROMATIC HYDROCARBONS, AND ITS CATALYST" |
|---|---|
| Abstract | The present invention relates to a process of the disproportionation and transalkylation of toluene and heavy aromatic hydrocarbons of nine and more than nine carbon atoms and also to a catalyst used in the process. It can be mainly used to overcome the disadvantges of the known process in the prior arts. The said disadvantages include that the processing quantity of heavy aromatic hydrocarbons is lower; only the dealkylation and lightening are carried out in the known process in the prior arts resulting in a large amount of non-aromatic light hydrocarbons and the stringent requirement on the composition of feedstock is needed. The present invention can be used to effectively carry out the disproportionation and transalkylation of toluene and heavy aromatic hydrocarbons of nine and more than nine carbon atoms by using the catalyst made of zeolite and molybdenum oxide and other active components supported on the zeolite so as to form a large quantity of benzene and xylene products. In addition, the catalyst of the present invention is of such characters as high catalytic activity, a great processing capacity of heavy aromatic hydrocarbons of ten and more than ten carbon atoms and high selectivity to desired products of benzene and aromatics of eight carbons, so the presents invention can be successfully used in the industrial production. |
